我想通過iPython更新sqlite3數據庫。 我可以成功地將數據插入到數據庫中，但是當我嘗試更新一行將返回下面的錯誤對我道：python sqlite3更新語句返回鎖定錯誤
---------------------------------------------------------------------------
OperationalError Traceback (most recent call last)
<ipython-input-160-6483798c376d> in <module>()
2 conn.text_factory = str
3 conn.execute("update series set html='test123' where url='https://www.google.com/'")
----> 4 conn.commit()
5 print "Total number of rows updated :", conn.total_changes
OperationalError: database is locked
我使用的Python代碼如下。
conn = sqlite3.connect('mydb.db')
conn.text_factory = str
conn.execute("update series set html='test123' where url='https://www.google.com/'")
conn.commit()
print "Total number of rows updated :", conn.total_changes
我在做什麼錯？
